How to Display a Calendar on a Mac Desktop
When you have a lot of appointments and other items on your company’s schedule that you want to keep on top of with your Mac, you can display a calendar on the desktop. All new Macs come with Apple’s free Calendar application already installed. You can view the calendar in full-screen mode, and if you want to use it as your desktop image, you can use Apple’s native screenshot application to save a picture of the calendar, enabling you to see your appointments even if you aren’t running the Calendar application.
